Another Tkinter question

[dsavitsk]

I have a small tkinter app that contains a (PMW) ScrolledFrame which in turn
has a grid of entry widgets (it sort of emulates a small spread sheet).
What I would like to do is add a new row of entry widgets while the thing is
running, and I'm not sure how to go about this as I've already .packed them
in.  (Also, if anyone knows a better way to do this than tons of entry
widgets that would be great.)

I can put some of my code up if need be.

thanks,
